For me the grip dimensions on the 17 and 19 gen 3 pistols are perfection. I even like the finger grooves.
The gen 4 versions with the medium backstrap is supposed to mirror the gen 3 grip but just does not feel the same to me.
There was no reason in the 9mm caliber for Glock to change the recoil assy. and the gen 3 triggers are indeed slightly better. I have never seen anyone get slide bite from a glock? so the beavertails are silly IMO.
The larger mag release of the gen 4 is not an advantage for me either (I run the vickers releases on all my gen 3's)
My vote for the best Glock is a factory gen 3 RTF 2 or a stippled grip regular gen 3 and in particular the 19 versions.
